If you take two balls randomly out of a jar of colored balls, there is a 50% chance that the balls will both be red.
What is the total percentage of red balls in the jar?

no, because once youve picked out 1 red ball, theres 1 less red ball to take out. so you need two fractions that equal 1/2 when multipied. 2/3 and 3/4 fit this, and it is the only answer to the problem.
